With uv_replace_allocator, it's possible to override the default
memory allocator's malloc and free calls with functions of the user's
choosing. This allows libuv to interoperate with projects requiring a
custom memory allocator.
Internally, all calls to malloc and free have been replaced with
uv__malloc and uv__free, respectively. The uv__malloc and uv__free
functions call malloc and free unless they have been overridden by a
previous call to uv_replace_allocator.
As part of this change, the special aligned memory allocations
performed in src/win/fs-event.c have been replaced with standard
allocations. The 4-byte alignment being requested in this file was
unnecessary, since standard allocators already guarantee at least an
8-byte alignment.

Before this commit, UNIX returned -1 on failure. Windows sometimes
returned a UV_E* error code and sometimes a bogus status code, courtesy
of errno values not mapping to UV_E* error codes on that platform.

Commit 393c1c5 ("unix: set non-block mode in uv_{pipe,tcp,udp}_open")
causes a regression in the io.js cluster module.
The io.js documentation states that `worker.send()` and `process.send()`
are synchronous but they no longer were after upgrading to libuv v1.2.1.
The reason they are synchronous is because of backpressure - or rather,
lack of backpressure: a slow consumer eventually causes a fast producer
to run out of memory because the backlog of pending messages in the
producer can grow unchecked.
Ergo, implement uv_stream_set_blocking() on UNIX platforms to let io.js
enable the old blocking behavior for pipes again.

libuv requires that the socket/fd is in non-blocking mode, so do it
internally so the user doesn't need to write platform specific code to
do so.
This also makes the API consistent with uv_{tcp,udp,pipe}_open, since
it's not required to pass the fd in non-blocking mode there either.

The contract specifies that the file descriptor should already be in
non-blocking mode before passing it to libuv.
However, node users don't really have an opportunity to do so, never
mind the fact that the call to uv_pipe_open() or uv_tcp_open() is an
implementation detail that most users won't be aware of.
Let's be nice and set the non-blocking flag explicitly. It's a cheap
operation anyway.

59658a8de7 changed uv_thread_self()
to return uv_thread_t, but uv_thread_t is a thread's HANDLE while
uv_thread_self() returns the current thread's id.
This means that uv_thread_equal() is also broken, as we are
potentially comparing HANDLES to ids.
Changed uv_thread_self() to return the current thread's creation handle.
Fixed small doc issue.
